Pygit2 cannot parse URLs with OAuth tokens.

I'm trying to use pygit2 to clone a GitHub repo using OAuth tokens.
This actually works well from the command line, as explained on GitHub's blog here.

So, I do:

from pygit2 import clone_repository

oauth_token = 'somesuperlongtokengivenbygithub'
repo = clone_repository(
                'https://'+oauth_token+'@github.com/openwrt/luci', 
                '/tmp/repos', 
                bare=True
)

and I get back:

_pygit2.GitError: Unsupported URL protocol

Beginne mit dem in pygit2/init.py gezeigten clone_repository-Aufruf und untersuche, wie die URL die Fehlerprüfung in errors.py erreicht. Reproduziere den Fall mit der OAuth-Token-URL, vergleiche ihn mit dem im Issue beschriebenen Verhalten über die Kommandozeile und ermittle, welche bestehende URL- oder Authentifizierungsbehandlung greift. Als abgeschlossen gilt, dass clone_repository die dokumentierte GitHub-Token-URL akzeptiert, ohne Unsupported URL protocol auszulösen.
